Adobe Photoshop 1 Source Code Released for Free

If there's one piece of photo editing software that just about everyone seems familiar with, or at least acquainted with, it's Photoshop. Adobe's history in the space stretches back many years, and every new edition of the program receives huge amounts of attention as digital artists wait to see what kind of magic lies in the next-gen code. But what about the original code? It can now be yours if you want it. Way back in 1988, a program called "Display" was renamed "Photoshop," with Adobe agreeing to license and sell it in April of 1989. Over the next decade, over three million copies of the program were sold.

The v1.0 was written almost entirely in Pascal for the Apple Macintosh computer, and for the first time, it's being made available to the public at large. Adobe has given permission for the Computer History Museum to present the source code to the 1990 version (v1.0.1) of Photoshop. Of course, it's only for non-commercial use, but still -- all of the code is included with the exception of the MacApp applications library that was licensed from Apple. All told, you'll find over 179 files, with around 128,000 lines of code. Grab the Via link to get your download, and have fun!
